Installation help needed(64 bit or 32 bit)


Hi ,
I have to install Oracle Enterprise linux 64bit version on my machine.

How would i determine whether my system is compatible for 64 bit version.

What is difference between 64 bit version and 32 bit version?

I heard that 64 bit version are suitable for machine with ram more than 4 gb is it true?

Try

uname -a

as root. If you see x86_64 as part of the output, it's a 64 bit OS. 32 v 64 bit means a larger address space. It's not necessarily faster. You can address larger amts of RAM more easily, see http://kbase.redhat.com/faq/docs/DOC-6571

You can get all 32-bit apps to run on a 64-bit system. You can't get all 64-bit apps to run on on a 32-bit system. If you are running 'Oracle Enterprise linux 64bit version' then you have a 64-bit system. I would stick with it. Otherwise, performance would take a hit.

Cheers, Lou
